Hi

I saw board has 2 usb ports, 2 ethernet ports and a mini usb port.
When I plug in mini usb port to PC, from Linux I can picocom /dev/ttyUSB2 -b 115200.
it shows eth0, eth1, and 2 wlan0, wlan1 etc, what are they.
Where are the external 2 ethernet ports, 2 usb ports in Linux system?

If I set eth1 an IP address, try to connect to local PC, it won't work?

Sorry lots of questions.
